A machine is disclosed. The machine may include at least one of a propulsion system or a steering system configured to operate under automatic control in an autonomous mode of the machine; and a controller configured to obtain one or more parameters associated with a task that is to be performed in the autonomous mode, determine an estimated completion time for the task based on the one or more parameters associated with the task, and perform one or more actions based on the estimated completion time for the task.

A machine has a chassis and at least one propulsion device configured to support the chassis. The machine also has a machine control module configured to control operations of the machine. Further, the machine has a modular sensor bay configured to be attached to the chassis. The modular sensor bay includes a position sensor configured to determine a position of the machine. The modular sensor bay also includes an imaging device configured to generate an image of at least a portion of surroundings of the machine. The modular sensor bay includes a control module configured to control operations of position sensor and the imaging device. In addition, the modular sensor bay includes a harness configured to electrically connect the modular sensor bay with the machine control module.

A compaction drum can include an outer surface defining a width. The compaction drum also can include a plurality of pads disposed on the outer surface of the compaction drum and positioned in at least one row. Each of the plurality of pads can be disposed circumferentially spaced apart relative to one another on the outer surface. Each of the plurality of pads can define a first height. The compaction drum further can include a plurality of ribs disposed on the outer surface. Each of the plurality of ribs can be connected between adjacent pads of the plurality of pads. Each of the plurality of ribs can define a second height. The second height of each of the plurality of ribs can be approximately equal to the first height of each of the plurality of pads.

A fluid spray system for a compaction machine is provided. The fluid spray system includes at least one nozzle adapted to deliver a flow of fluid adjacent to a compaction member. The fluid spray system includes a fluid pump adapted to provide the flow of fluid to the at least one nozzle. The fluid spray system includes an operator interface configured to generate a signal indicative of activating a test mode based on an operator input. The fluid spray system includes a controller configured to receive the signal from the operator interface. The controller is also configured to activate the fluid pump for a predefined time period to provide the flow of fluid to the at least one nozzle. The controller is further configured to deactivate the fluid pump based on elapsing of the predefined time period to limit the flow of fluid to the at least one nozzle.

A ROPS (protective structure) (15) is obtained by coupling upper ends of a pair of leg portions (15a) with a coupling portion (15b) and forming an arc-shaped curved portion (15c) between each of the leg portions (15a) and the coupling portion (15b), and is arranged so as to straddle vehicle bodies (4 and 5) and fixed. A working light (17) is fixed to the left curved portion (15c) via a mounting bracket (19), and a rotary light (18) is detachably mounted by fixing a mounting bracket (20). A protect region (E) formed into an approximately triangular shape is formed by the curved portion (15c) of the ROPS (15), a lateral restriction line (L1) in which a left-side surface corresponding to a maximum width of the vehicle bodies (4 and 5) is extended upward and an upper restriction line (L2) in which a maximum height of the ROPS (15) is extended laterally. The working light (17) and the mounting brackets (19 and 20) are arranged in the protect region (E), thereby preventing an outward protrusion.

A method for preparing a paving material includes heating an aggregate comprising recycled asphalt pavement using an emitter generating electromagnetic radiation having a wavelength of from 2 microns to 1 millimeter. The method utilizes solid phase autoregenerative cohesion to prepare a material suitable for use as an aggregate in a hot mix asphalt pavement installation.
